Paper presented at the SPE Canada Heavy Oil Technical Conference, March 13–14, 2018
Paper Number: SPE-189745-MS
... Abstract Whereas polymer flooding is now a proven method for heavy oil reservoirs, the use of surfactants is reported only in a limited number of cases and mostly in combination with alkali (ASP) to benefit from in-situ generated soaps. Operational issues such as scale formation, corrosion...

..., with the production of 30% of the bitumen in two weeks. Bleakly (1984 ) reported a field test of the IITRI process in a shallow heavy oil reservoir in Oklahoma. Sresty et al. (1986 ) reported on the measurement of electrical and petrophysical properties of tar sand samples from the field pilots. Marsden (1991...

... is a preferred EOR technique in such reservoirs. An application of polymer flooding in heavy oil reservoirs dates back to more than half a century ago. However, it has long been considered a suitable method for reservoirs with viscosities up to 100 centipoises only. Recently, this EOR technique has attracted...

..., or a reduction of total production rate or both. As both interventions reduce the economic returns, most projects operate with incomplete voidage replacement (VRR < 1). We have previously reported that a VRR < 1 improves the waterflood response of heavy oil reservoirs. Thus using the VRR = 1 waterflood...

... Abstract Inflow control devices (ICDs) improve oil recovery because of their capability to delay water and gas breakthrough. ICDs also can be applied to heavy oil reservoirs to help overcome the higher mobility of water, and therefore, are now frequently used in Canada's Steam-Assisted Gravity...
